Glycine betaine aldehyde, often simply called betaine aldehyde,[1] is an intermediate in the metabolism of glycine, serine and threonine. The human aldehyde dehydrogenase (EC 1.2.1.3) stimulates the transformation of betaine aldehyde to glycine betaine. Betaine aldehyde is a substrate for choline dehydrogenase (mitochondrial).[2]

Chemical structure[edit]

Glycine betaine aldehyde is a short chain aldehyde and quaternary ammonium compound. It can be considered a derivative of the amino acid glycine. Its chemical formula is C5H12NO+.

Biological function[edit]

Glycine betaine aldehyde is a component of glycine, serine and threonine metabolism. It also serves as an osmolyte.

It can be found in cytoplasm and mitochondria within the kidney, neurons, and stratum corneum.[3]
